Omega Seamaster Aqua Terra 150M Co-Axial Chronometer "15000 Gauss" 41.5mm Stainless Steel Black Dial Leather Strap 231.12.42.21.01.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most enduring lines in the Seamaster family, conceived to bridge the worlds of professional aquatic performance and refined everyday elegance. The name '150M' reflects the collection's water resistance heritage, while the Aqua Terra identity — evoking both water and land — signals a watch equally at home on a yacht deck or in a boardroom. Reference 231.12.42.21.01.001 represents one of the most technically ambitious expressions of this lineage, distinguished by the legendary '15000 Gauss' designation that has made it a benchmark in modern horology.

At 41.5mm in stainless steel, the case presents a commanding yet wearable profile on the wrist. The white gold bezel elevates the piece beyond typical sports-watch territory, lending it a sense of precious-metal luxury that contrasts beautifully with the deep black index dial beneath. The horizontal 'teak' pattern on the dial, a hallmark of the Aqua Terra line, adds subtle texture and depth that rewards close inspection, while the index hour markers provide immediate, unambiguous legibility at a glance.

The movement housed within this reference is a Co-Axial Chronometer, Omega's proprietary escapement technology developed in collaboration with master watchmaker George Daniels. The Co-Axial mechanism dramatically reduces friction between escapement components, resulting in longer service intervals and exceptional long-term accuracy compared to traditional lever escapements. Certified as a Chronometer by the COSC, it meets stringent independent standards for precision timekeeping.

The defining technical achievement of this specific reference, however, is its resistance to magnetic fields of up to 15,000 gauss — a figure that dwarfs conventional watch specifications, which typically manage 60 to 80 gauss at best. Omega achieved this through the use of non-ferromagnetic materials within the movement's critical components, eliminating the need for a traditional soft-iron inner case. The result is a watch with full transparency through a sapphire crystal caseback, exceptional accuracy in modern environments saturated with electromagnetic fields, and a horological milestone that changed industry expectations.

Finishing the package is a supple leather strap that lends a dressy, versatile character to this performance-pedigree timepiece. The strap complements the white gold bezel and black dial combination, making reference 231.12.42.21.01.001 equally suitable as a daily companion or a special-occasion watch. Whether paired with a suit or weekend casual wear, the Aqua Terra '15000 Gauss' transitions with effortless authority.
